VELOCI PEDE-PE DAL.

SPECIFICATION forming part of Letters Patent No. 492,990, dated March7,1893.

Application filed October 22, 1892; Serial No- 449,603- (No model.)

, To all whom it may concern.-

Be it known that I, CHARLES F. PEASE, a citizen of the United States,residing at Ohicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Velocipede-Pedals; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to letters or figures of referencemarked thereon, which form a part of this specification.

My improvement has for its object the sealing of the free end of thepedal, whereby waste of oil from the hub of the pedal and entrance ofdust and sand to the hub of the pedal may be prevented.

In the accompanying drawings, Figure 1 is a plan of a pedal embodying myimprovement. Fig. 2 is a section in line a-b of Fig. 1.

A, is a portion of the arm supporting the pedal.

A, is the pedal axle. This is applied to the arm, A, in any suitablemanner.

B, is the hub of the pedal. This surrounds the axle, A and may or maynot be separated from thelatter by means of balls, B. If such balls areused, the ends of the hub must be provided with annular oblique faces,b, arranged in opposition to similar oblique faces, a, supported by theaxle, A, in the well known manner, the face, a, at the free end of thepedal being formed on a nut, A surrounding the axle, A, and engagedthereon by threads, of, on the axle, A. Outside of said nut and alsosurrounding the axle, A, may be the usual washer, A and the jam-nut, Afor binding the nut, A after the proper adjustment v of the bearing hasbeen made.

The hub, B, may be composed of a single piece or it may be composed of atubular part, 1, and the expanded annular end-pieces, 2, extending overthe ends of the tube, 1, and resting against the shoulders, 3, on saidtube.

0, is the end-plate at the free end of the pedal.

O, is the end-plate at the end of the pedal located next to the arm, A.At the free end of the pedal, the end of the hub has an annular seat, 0directed toward said free end.

0 is a dome-shaped cup extending over the free end of the axle, A, thenuts, A and A and the washer, A to the end of the hub and resting by itsbase against the said annular seat, 0 At the base of said dome, there ispreferably formed, integral with said dome, a narrow flange, 0 extendingoutward from said dome parallel to and in contact with said seat, 0 Saidflange constitutes an expanded base.

The end-plate, O, is open at its middle sufficiently to extend over andfit snugly around the base of the dome, O and against the flange, c andbind said dome against the hub, B. Bolts, D, extend from the end-plates,C, through the end-plates, O, and bind the latter against said dome.Suitable foot pieces, D, are secured by the bolts, D. It will be seen,that said dome becomes a portion of the r0- tary part of the pedal, andthat by its use the free end of the pedal is entirely sealed againstescape of oil and against ingress of dust and sand. It is also to beobserved, that the construction described is neat and simple; no

threading or difficult shaping being required to fit the end-pieces, 2,to the tube, 1, or to fit the dome, O and the end-plate, O, to the endof the hub. The end-pieces, 2, may be formed by drop forging or ordinarylathe work, and the dome, 0 may be made by drop forging, stamping,spinning, or turning. The endplates, 0, may be formed by drop forging orstamping.

In re-adjusting the bearing of the pedal, the end-plate, C; and thedome, 0 are removed.

I claim as my invention-- 1. In a pedal,the combination with an axle,

hub, a dome surrounding the free end of said axle and said nut andhaving an expanded base resting upon said seat, an end-plate surroundingsaid dome and resting against said expanded base, substantially as shownand described.

3. In apedal, the combination with the axle,

A, and a hub consisting of a tubular part,1,

and end-pieces, 2, of a nut, A a dome, C havin g an expanded base,end-plate, 0, extending over said dome and resting against said base,end-plate, 0, located at the end of the pedal to which the pedal arm isto be attached,and suitable connections as bolts, D, extending from theend-plate, O, to i the end-plate, C, substantially as shown anddescribed.

4. In a pedal, the combination with the ax] e,
